The functional response of the phytoseiid predator Chileseius camposi González y Schuster, 1962 (Acarina:Phytoseiidae) on densities of its prey Panonychus ulmi (Koch, 1836) was evaluated under controlled temperature (20 +/- 2 degrees C), relative humidity (75 +/- 15%) and photoperiod (16:8h L:D). A functional type II response was displayed (Holling's disk). Holling, Wolf transformation and Roge...

In the article, use of lacewing (chrysopa septempunctata wesmael) against apple red mite (Panonychus ulmi Koch), which is found in intensive orchards territory republic, at different consumption rates (1:5, 1:10, 1:15), based on its pest ratio and biological effectiveness. The results obtained are illuminated. By end season, number mites had been to have decrease 87.8%. Our research, less effec...

In order to contribute to taxonomic information on Tetranychid mites (Acari: Tetranychidae) in South America, surveys were conducted in Brazil (15 States and the Federal District) and Uruguay (one Department); 550 samples of 120 plant species were collected. Tetranychid mite infestations were confirmed in 204 samples, and 22 species belonging to seven genera of the Bryobiinae and Tetranychinae ...

Biological efficacy of rapeseed spray oil against twospotted spider mite (Tetranychus urticae Koch) on cucumber, against European red mite [Panonychus ulmi (Koch)] on apple, green peach aphid (Myzus persicae Sulzer) on pepper and pear psylla [Cacopsylla pyri (L.)] was evaluated in seven field and three greenhouse trials at eight localities in Serbia during 2005-2008. The efficacy of rapeseed sp...

study of the spatial distribution of a pest and its natural enemies provides better decision tool for integrated pest management. the spatial distribution and seasonal activity of panonychus ulmi (koch) and its predator zetzellia mali (ewing) were studied in an apple orchard in khoramdareh (zanjan province, iran) during 2007. the interaction (density dependence) between the prey and its predato...
